This study aid works from text you paste or open. It does not call an AI model and it does not invent facts. It splits your notes into sentences, scores them by word frequency and position, and builds a short summary, key terms, practice questions and flashcards. The output is a study draft, not a substitute for reading the source.

How to use it

Paste your own notes or reading. Use plain text. Remove passwords, private messages and anything you are not allowed to share. The tool runs locally, but you should still treat the text as sensitive.
Choose a task. Short notes, detailed notes, key terms, practice questions or flashcards. The task changes how much text is selected and how the output is arranged.
Generate. The tool reports how many words and sentences it used. If the input is too short, it says so rather than padding the result.
Check and edit. Copy the notes into your own document and correct anything that sounds awkward or incomplete. Questions are built from the source sentences; they are prompts for recall, not exam predictions.
Download or print. The output can be copied, downloaded as text or printed. Keep the source with it so you can verify the claims later.

What “extractive” means

An extractive summary selects existing sentences. It cannot paraphrase in the way a language model can, and it cannot add an explanation that was not in your notes. That is a limitation, but it is also a safety feature: every sentence in the summary should be traceable to something you supplied. If a sentence is confusing in the source, it may still be confusing in the summary.

The scoring favours sentences with repeated important words, useful length and an early position in the text. It is a simple heuristic, not a semantic understanding of your subject. A list of dates, a formula-heavy page or a table pasted as text may produce poor results. Clean up the input first: one idea per paragraph, headings on their own lines, and no repeated navigation text.

Good uses

Making a revision sheet from lecture notes you already wrote.
Pulling key terms out of a chapter summary before a quiz.
Creating recall prompts from your own explanations.
Reducing a long pasted article to a shorter reading list of sentences.
Checking whether your notes contain enough detail to answer a question.

Limits and honesty

No AI: there is no language model, no API key and no generated explanation. The interface says so.
English-oriented: the sentence splitter and common-word list are designed for English text. Other languages may work poorly.
Maximum input: the character limit is shown in the editor. Longer text is not silently truncated; the tool asks you to shorten it.
No citations: the output does not add references. You must keep track of where the source came from.
Not a plagiarism checker: it does not compare your work with other sources.
Not an exam predictor: practice questions are generated from sentences and may miss the most important idea.

Privacy

Your text stays in this tab. It is not sent to OmniEmu or to a third-party AI provider. The page loads its own files, but the text you type is not part of those requests. The text can remain in the form and in browser memory until you reset or close the tab. If you use a shared computer, reset the tool and close the tab when you finish.

Frequently asked questions

Is this AI?

No. It is a local extractive summariser and question generator. Calling it AI would overstate what it does.

Why does the summary repeat a sentence?

The selector tries to avoid duplicates, but short inputs or repeated source sentences can still produce repetition. Edit the input or remove duplicate lines, then try again.

Can I use my lecture slides?

Paste the text you are allowed to use. Images and diagrams are not read. A PDF of slides must first have its text extracted, and the result may contain headers, footers and slide numbers that need cleaning.

Are the questions multiple choice?

The current version creates short-answer prompts and flashcards. It does not generate reliable distractor options for a multiple-choice quiz. Treat the prompts as a recall aid and write your own options if you need them.

Does it save my notes?

No. There is no account and no server-side save. Download or copy anything you want to keep before closing the tab.
